## Summary
- Add `.claude/CLAUDE.md` with project guide, C++ coding style,
correction patterns from past AI interactions, and pre-commit/pre-PR
workflows
- Add `.claude/commands/` with `/build`, `/test`, `/format` slash
commands for Claude Code
- Add `.clang-tidy` configuration
- Add `scripts/run_clang_tidy.py` for parallel clang-tidy with progress
reporting (reads CDB, filters to `src/` and `tests/` only)
- Add pixi tasks: `clang-tidy`, `lint-cpp`, `lint-python`, `lint`
- Add `clang-tools` dependency for clang-tidy
- Update `.gitignore` to track `.claude/CLAUDE.md` and
`.claude/commands/`
## Test plan
- [x] `pixi run format` passes
- [x] `pixi run lint-python` passes (ruff check)
- [x] `scripts/run_clang_tidy.py` correctly filters to project files
only
